Abstract
A separator for a secondary battery including a porous separator substrate including a polymer; and a coating layer on at least one surface of the porous separator substrate. The coating layer includes a crystalline first binder and a noncrystalline second binder. The crystalline first binder and the noncrystalline second binder are independently an aqueous emulsion type binder, thereby ensuring adhesion strength between the separator and a positive electrode and between the separator and a negative electrode even in the presence of an electrolyte solution.
